continu-IRON HEATER.

Application filed October 29, 1926. Serial No. 145,027. i

rl`his invention relates to curling iron heaters, of the gas type, and has for its object to provide, a heater of such class including means, in a manner as hereinafter set forth, for supporting the iron when being heated in a manner so it can be conveniently grasped and removed by the operator from the heater; with means in a manner as hereinafter' set forth, for materially increasing the flow of gas to the burner element of the heater and with such means actuated by the iron when the latter is mounted in position to be heated; and with means for materially reducing the flow of gas to the burner element of" the heater when the heated iron is removed and with the last mentioned means automatically operating to reduce the flow of gas to the burner element. e

Further objects of the invention are to provide a curling iron heater, in a manner as hereinafter set forth, and which 1s simple in its construction and arrangement, strong, durable, compact, thoroughly etcient in its use, automatic' in its action to reduce the flow of gas to the burner elements thereof, readily assembled, pleasing in appearance, and comparatively inexpensive to manufacture.

lith the foregoing and other objects in view, the invention consists of the novel co-nstruction, combination and arrangement of parte as hereinafter more specifically .described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invent-ion, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is an end elevation of a curling iron heater in accordance with this invention.

Figure Q is a section on line 2-2 Figure 1 and' further illustrating a curling iron mounted on the heater and with the curling iron shown in dotted lines.

Figure 3 is a. top plan view of the heater.

Referring to the drawings in detail 1 denotes a base, preferably of circular formand of the desired diameter and which is provided on its upper face, centrally thereof, with a vertically disposed collar 2, having the inner face thereof threaded throughout as at 3. The upper face of the base 1 centrallythereof is provided with a socket a and said collar 2 forms a continuation of the wall of the socket. The wall of the socket 4 is threadedthroughout.

Detaehably engaging with the base 1, is a tubular pedestal 5 having the periphery thereof, at its llower end, formed with threadsv G which engage with the threads whereby the pedestal 5 is detachably connected to the base 1 and supported in upright position by the latter. The pedestal 5 has its inner face intermediate its ends formed with an integral annular flange 7 which is beveled as at 8 to provide a valve seat. The pedestal G below the flange 4, and in proximity to its lowerV end is provided with an inlet'opening 9 with which communicates a right angularly disposed, pe-ripherally threaded nipple 10 which is employed for connecting gas supp-ly line'to the heater. The gas supply line is not shown.

Formed integral withthe upper end of the pedestal 5, as well as communicating therewith, is a burner element of rectangular contour and which is referred to generally by the reference character 11, and which includes a bottom. 12, a pair of end walls 13, lll, a pair of side walls 15, 16 and a top wall 17 formed with a pair of spaced rows of spaced ports 18. Each rowof ports is positioned in the top wall 17 in proximity to the inner'face of the side wall of the element 11. The bottom 1Q, between its transverse median and one end thereof is formed with an opening 1S,'and the tubular pedestal has its upper end formed integral with the outer face of the bot-tom 12, and the inner face ofthe pedestal 5 is flush with t-he wall of the opening 18.

Formed integral with the end wall 14 is a support 19, which is disposed transversely with respect to the element 11 and projects a substantial distance thereabe-ve; The support 19 is of a length greater than'the width of the element 11 and is provided in its top edge with groove 20 to receive one end of the curling iron 21. Formed integral with the end wall 13 and extending in a direction at right angles to saidwall, is lanarm 22, of less width than t-he width ofthe element 11 and of a length to projecta substantial distance beyond thebase 1. The arm 22 is fiat and has its outer end formed integral with a. support 23, which isv disposed transversely with respect to the element 11 and extends a substantial distance thereabove. The. support 23 is of greater length than the support 19 and is grooved as at it to receive the handle end ot the curling iron.

Cooperating with the flange 7, is a gas llow controlling valve Q oil tapered torni and t'he size oit the yalve 25, relative to the seat S, is such that when the heater is not employed for heating the iron, the flow of gas to the burner element will be materially reduced. The reduction ot the tlow of gas is had when the valve is in its lowermost position, as shown in Figure Q. rlhe valve 25 is shifted upwardly, to increase the llow ot gas to the burner element 11, when the iron 21 is in position to be heated, or in other words, when the iron Q1 mounted on the supports 19, 23, as well as upon a shitting means tor the valve 25. The. re'i'erence character QG denotes a vertically disposed valve stem ot cylindrical cross section, and which has its lower end tornied integral with the enlarged upper end ot' the valve The stem 2G extends up through the pedestal 5. opening` 18, through the gas receiving chamber 27 formed by the element; 11, and farther extends through an opening 2S formed in the top wall 17 ot t-he element 11. The opening Q8 is arranged centrally between the rows ot jet openings 18. rl'he stem projects a substantial distance above t'ie top wall 17 ot' the element 11, and is formed with a biturcated upper end 2S. The top wall 17, o1 the element 11, between the opening and support 19 is provided with a pair ot` vertically disposed apertured ears Q9, between which is arranged a lever 30, the latter is pivotally connected with the ears Q9 by a pin 31. One end ot' the lever has a pin and slot connection 32, with the upper end of the stem 2G, and the other end of the. lever 10 is `formed with an upstanding semi-circular tool cngaging portion 32. interposed between the. end of the lever 30, which is provided with the portion 32', and the upper face oit' the wall 17 of the element 11` is a controlling spring 33 for the lever 30. l'hc stem Qt, lever and spring 33 provides a spring controlled shitting means i'or the valve vWhen the iron Q1 is in the dotted line position Ishown in Figure 2, the weighty thereof will rock the lever il() on its pivot. against the compression of the spring $33, whereby the stem QG will be elevated and the valve 25 moved upwardly to increase the tlow of gas to the burner clement 11. Then the iron 21 is removed from engagement with the portion 32 on the lever 30, spring 33 acts to rock the lever 39 in the opposite direction thereby lowering the stein 2G, which will carry the valve 25 therewith, and materially reduce the How of gas to the burner element.

It is thought the many advantages of a curling iron heater, in accordance with this invention can be readily understood, and although the preferred embodinient ol' tl i invention is as illustrated and described, yet it; is to be understood that. changes in the details oi construction can be had which will Ytall within the scope of the invention as claimed.
